AdWords is flagship advertising product and main source of revenue ($16.4 billion in 2007). AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. AdWords text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.

Pay-Per-Click advertisements (PPC)

Advertisers specify the words that should trigger their ads and the maximum amount they are willing to pay per click. When a user searches p2minfotech search engine on www.p2minfotech.com or the relevant local/national server ,ads (also known as creative by p2minfotech) for relevant words are shown as "sponsored links" on the right side of the screen, and sometimes above the main search results.

The ordering of the paid-for listings depends on other advertisers' bids (PPC) and the "quality score" of all ads shown for a given search. The quality score is calculated by historical click-through rates, relevance of an advertiser's ad text and keywords, an advertiser's account history, and other relevance factors as determined by p2mInfotech. The quality score is also used by Google to set the minimum bids for an advertiser's keywords. The minimum bid takes into consideration the quality of the landing page as well, which includes the relevancy and originality of content, navigability, and transparency into the nature of the business. Though p2mInfotech has released a list of full guidelines for sites, the precise formula and meaning of relevance and its definition is in part secret to Google and the parameters used can change dynamically.

The auction mechanism that determines the order of the ads has been called a "generalized second price" auction. It is similar to the Vickrey auction, but is not equivalent to the Vickrey-Clarke-Groves (VCG) mechanism and hence truth telling is not an optimal strategy.

Placement targeted advertisements (formerly Site-Targeted Advertisements)

In 2009 p2mInfotech introduced site-targeted advertising. Using the AdWords control panel, advertisers can enter keywords, domain names, topics, and demographic targeting preferences, and p2mInfotech places the ads on what they see as relevant sites within their content network. If domain names are targeted, Google also provides a list of related sites for placement. Advertisers may bid on a cost per impression (CPI) or cost per click (CPC) basis for site targeting.

With placement targeting, it is possible for an ad to take up the entire ad block rather than have the ad block split into 1 to 4 ads, resulting in higher visibility for the advertiser..

AdWords distribution

All AdWords ads are eligible to be shown on www.p2minfotech.com. Advertisers also have the option of enabling their ads to show on www.p2minfotech.com. partner networks. The "search network" includes AOL search, Ask.com, and Netscape. Like www.p2minfotech.com. these search engines show AdWords ads in response to user searches.

The "content network" shows AdWords ads on sites that are not search engines. These content network sites are those that use AdSense, the other side of the p2mInfotech advertising model. AdSense is used by website owners who wish to make money by displaying ads on their websites. Click through rates on the content network are typically much lower than those on the search network and are therefore ignored when calculating an advertiser's quality score. It has been reported that using both AdSense and AdWords may cause a website to pay p2mInfotech a commission when the website advertises itself.

p2mInfotech automatically determines the subject of pages and displays relevant ads based on the advertisers' keyword lists. AdSense publishers may select channels to help direct p2mInfotech’s ad placements on their pages, to better track performance of their ad units. There are many different types of ads you can run across p2mInfotech’s network, including text ads, image ads (banner ads), local business ads, mobile text ads, and in-page video ads.

AdWords account management

To help clients with the complexity of building and managing AdWords accounts search engine marketing agencies and consultants offer account management as a business service. This has allowed organizations without advertising expertise to reach a global, online audience. Google has started the p2mInfotech Advertising Professionals program to certify agencies and consultants who have met specific qualifications and passed an exam. Google also provides account management software, called AdWords Editor.

Another useful feature is the My Client Centre available to p2mInfotech Professionals (even if not yet passed the exam or budget parameters) whereby a Google professional has access and a dashboard summary of several accounts and can move between those accounts without logging in to each account.

Click-to-Call

Google Click-to-Call was a service provided by p2mInfotech which allows users to call advertisers from Google search results pages. Users enter their phone number p2mInfotech calls them back and connects to the advertiser. Calling charges are paid by p2mInfotech. It was discontinued in 2007
